Post-COVID condition is the presence of new, recurring, or ongoing signs and symptoms for greater than four weeks after a SARS-CoV-2 infection. Persistent headache as a neurologic sequalae of COVID-19 infection is a common prolonged symptom with limited characterization in the literature. This was a case of a 27-year-old female diagnosed with mild COVID-19 who presented with fever, colds, fatigue, headache, decreased hearing, sore throat, dry cough, pleuritic chest pain, anosmia, ageusia, myalgia, and severe low back pain. Headache was described as remitting, frontally located, squeezing and moderate to severe in pain intensity. She was admitted in a tertiary COVID referral hospital for 8 days and was managed supportively. On the 10th day of illness, symptoms had resolved except for an on and off headache. The residual recurrent headache lasted for more than 5 months after being tested negative for SARSCOV2 on repeat reverse transcriptase-polymerase chain reaction (RT-PCR). The possible pathophysiologic mechanisms for neurologic manifestations and prolonged headache were hypoxia, endothelial damage through angiotensin converting enzyme receptor, and cytokine reactions. The characteristics of the symptoms remained unclear despite the proposed mechanisms for prolonged headache among COVID-19 patients.

DNA profiles have been increasingly used as the most reliable means to identify remains from war or mass disaster. To establish the identity with such a large set of victims, special care should be taken to correlate remains with correct family references while avoiding coincidental match between non-relatives. Therefore we address here relevant statistical and combinatorial issues in the DNA identification of mass victims. A simple and general formula for the likelihood ratio governing any potential kinship between two DNA profiles was presented, and for that purpose, the probabilities that a given relative and an individual share autosomal identical-bydescent alleles were calculated. In addition, a method dealing with the allele drop-out in kinship analysis and the estimation of a cold hit were discussed.

PURPOSE: The purpose of this study is to fabricate the new zirconia block (CNU block) and to evaluate fit of core and porcelain veneered zirconia crown. MATERIAL AND METHODS: The experimental blocks were fabricated from the commercial ytrria-stabilized zirconia powder (KZ-3YE Type A). The powder was uniaxial pressing and the green bodies were conducted using the Cold Isostatic Pressing. The zirconia blocks were presintered at 1040degrees C and the final sintering was performed at 1450degrees C. The Kavo Everest ZS blank(R) (KaVo, Biberach/Ri beta.) was used as a control group. The linear shrinkage of CNU block and Kavo block were compared. Twenty-one cores for porcelain veneered crowns were fabricated with CAD/CAM system (Everest(R), Biberach/Ribeta.). Group I: seven cores fabricated from Kavo blocks, Group II: seven cores fabricated from CNU blocks, Group III: seven cores from CNU blocks and porcelain veneering for crowns. All specimens were cemented and sectioned into two planes: diagonal and bucco-lingual. The measurement of the marginal, internal, and occlusal fit was carried out using SEM (S-4800(R)) at 30 x. The results were analyzed by one-way ANOVA test. RESULTS: The linear shrinkage of the CNU block and the KaVo block was 19.00% and 20.09%. The marginal gap of cores (29.67 +/- 6.58 micrometer) fabricated from CNU blocks showed significantly smaller than that of the cores of Kavo blocks (36.84 +/- 7.18 micrometer) (P < .05). The internal gaps of the porcelain veneered crowns (32.23 +/- 6.33 micrometer) were larger than those of the other two groups (37.57 +/- 6.81 micrometer and 38.14 +/- 6.81 micrometer). CONCLUSION: No statistically significant difference was found in between experimental groups and control group. The experimental groups in marginal gap showed significantly smaller than the control group.
